From The Farmington Daily Times (Mike Easterling):
While monsoon season does not conclude officially until the end of September, it is clear the summer weather pattern that typically brings a good deal of moisture to the Southwest has helped ease the drought’s grip on much of New Mexico.
Chuck Jones, a meteorologist with the National Weather Service in Albuquerque, said the agency will not have figures on monsoon rain totals until early October, after the season has drawn to a close.
But a look at the U.S. Drought Monitor map for New Mexico — and the rest of the Southwest — shows substantial improvement over the past two and a half months. Many parts of the state that were bone dry at the beginning of summer have emerged mostly, or even entirely, from the drought.
Nowhere has that change been more dramatic than in the southeast corner of the state. According to the Southwest and California Drought Status Update issued June 24 by the federal government’s National Integrated Drought Information System, parts of seven counties in that corner of New Mexico were characterized as being in exceptional drought — the worst category — and every county in that region was suffering from severe, extreme or exceptional drought, the three worst categories.
Now, two and a half months later, the picture there is much different, as portions of six of those counties are now characterized as normal. Much of the remaining territory in the southeast corner of the state is classified as being only abnormally dry or experiencing moderate drought.
While other parts of the state also saw marked improvement — portions of 13 counties in New Mexico now are drought free, compared to parts of just two counties on June 24 — others have not been so fortunate. Many parts of central, southwest and northwest New Mexico that were locked in drought at the beginning of the summer remain that way, even though their status has improved, as well.
The drought continues to take a heavy toll on San Juan, McKinley, Rio Arriba, Bernalillo, Santa Fe, Las Alamos, Catron, Grant, Hidalgo and Luna counties, with each of those counties still showing substantial territory characterized as being in extreme drought, the second-worst category.
That’s not to say those locations are as bad off as they were even a month ago, when large portions of all those counties were experiencing exceptional drought. In fact, the percentage of the state that is classified as being in exceptional drought has declined from more than 50% at the start of 2021 to approximately 33% three months ago, 4.5% on Aug. 10 and 0% on Sept. 9. And while 21.2% of New Mexico was in extreme drought on Aug. 10, that percentage declined to 19.1% by Sept. 7.
According to drought.gov, this was the 32nd wettest August in New Mexico over the last 127 years. Las Cruces has enjoyed an especially good monsoon so far, having racked up 5.06 inches of precipitation over that period, the third-wettest monsoon on record, according to drought.gov.
San Juan County has not seen that kind of bounty, but it has experienced a relatively good monsoon season, at least by the paltry standards of recent years. Jones said Farmington has received 1.6 inches of moisture at Four Corners Regional Airport over the three-month period, a figure that nearly matches the 30-year average of 1.62 inches.
For the year, Farmington has drawn 4.31 inches of precipitation, which comes close to matching the figure of 4.68 inches the city has received on average through the end of August for the last 30 years. Over the last three decades, Farmington has averaged a total of 7.76 inches annually.
As of Sept. 7, the vast majority of San Juan County was still characterized as being in extreme drought, with only slivers of the southwest and southeast corners in severe drought. But on Aug. 10, approximately half the county was in exceptional drought, and now none of it is.
